  • 48 GB capacity matches server memory controller expectations for full-speed operation
  • DDR5 4800 speed with CL40 latency runs at rated performance on compatible systems
  • Registered ECC architecture offloads the controller and corrects single-bit errors automatically
  • 288-pin RDIMM form factor fits Supermicro H13DSH motherboard memory slots precisely
  • 1 V operating voltage aligns with platform requirements for stable enterprise workloads

Compatible Supermicro H13DSH Upgrade

This 48GB DDR5 registered ECC module is built for the Supermicro H13DSH motherboard. It delivers the exact rank, voltage and timing the platform expects for full-capacity recognition.

Registered DDR5 Population Limits

Registered architecture allows every slot to run fully populated at the rated 4800 speed, but the motherboard manual decides maximum capacity, population order and supported ranks per channel.

48GB 2Rx8 CL40 Single Module

The single specification that decides fitment is the 48GB 2Rx8 CL40 1.1V registered DDR5 module; only systems qualified for this exact density and rank organisation will operate correctly.

Questions about this item

Should I choose the 48GB DDR5-4800 2Rx8 CL40 module or a different capacity for my Supermicro H13DSH?

Select the 48GB 2Rx8 Registered ECC module to match the board's memory-population rules; other capacities or ranks may not be recognised at full speed.

What does the 4800 MT/s rating deliver once the DIMM is installed in the server?

The module runs at DDR5-4800 (PC5-38400) with CL40 latency at 1.1 V, providing the exact bandwidth and timing the H13DSH memory controller expects.

How does the 288-pin RDIMM interface limit performance in practice?

The registered 288-pin DDR5 RDIMM interface buffers address and command signals, allowing every slot to be populated at the rated 4800 MT/s without overloading the controller.
